VECTOR IDENTIFIED!
Traps were placed at the locations listed on the trapping protocol page. The collections from these traps were identified and cross referenced with the list of potential vectors. There were three potential vectors that have now been narrowed down to one vector: Ixodes pacificus. This tick was determined to be the vector due to its presence in all locations that the traps were placed. The total specimens of this species collected was 5,670. Please see the excel spread sheet for more information.

Three Potential Vectors
Of the eleven vectors collected by patients, we have narrowed potential vectors down to three based on the fact that the following three were included in all four of the collections of the patients.
Ornithodoros coriaceus
Description given by patients: "Female. Four pairs of walking legs. Abdomen well developed, not constricted or distinctly segmented. Body without hair. Haller’s organ present. No scutum. No ventral shield; mouthparts of adult not prominent from above; pulvillus not present in adults. Hypostome of various forms but never scoop-like; associated with many different types of animals, including bats. Integument of adults and nymphs essentially alike, mammillated or tuberculated and lacking spines; hypostome of various forms in nymphs and adults but not vestigial. Lacking a definite sutural line separating dorsal and ventral surfaces. Eyes present. Dorsal humps on tarsi I present. Dorso-ventral grooves present, capitulum subapical. Cheeks absent." |
Ixodes pacificus
Description given by patients:
"Female. Four pairs of walking legs. Abdomen well developed, not constricted or distinctly segmented. Body without hair. Haller’s organ present. Scutum present; sometimes ventral shield present; mouth parts of adult prominent from above; pulvillus present. Ventral surface mostly covered by seven chitinous, non-salient plates; anal plate limited by distinct groove extending anteriorly around anus; anal groove extended to hind margin; scutum inornate; eyes and festoons absent. Cornua absent. Scutum lacking a group of deep, distinct punctations near the posterior margin. Lateral carinae on scutum absent. Scutum approaching circular. Auriculae not retrograde; indefinite or absent; when present, as rounded lateral extensions. Internal spur on Coxa I long. Hypostome with files 3 extending for more than half the length, files 4, 5, and 6 present. " |
Aedes vexans
Description given by patients:
"Three pairs of walking legs. One pair of wings present, moveable upon the thorax, with more than one vein. Only mesothoracic wings fully developed; metathoracic wings sometimes present as stubs or completely absent Mesothoracic wing not horny, leathery, or parchmentlike, usually membranous and transpartent, but may be covered with scales or hairlike setae or pigmented; always essentially similar in texture of membrane to metathoracic wing when latter is present. Pronotum greatly reduced, usually invisible from above, and at most represented by narrow transverse neck-like area; mouthparts haustellate, enclosed in a non-segmented labium or greatly reduced; abdomen without apical processes. Proboscis long, extending far beyond clypeus; scales present on wing veins and wing margin, usually also on body. Wings usually long and narrow, or if broad not pointed apically, and not densely h air although scales may lie along the wing veins or wing margin; Rs with 3 or fewer branches, M 2-branched. C continuing around wing tip, through often weaker behind. Wings narrow, with extensive venation. Antennae normal sized (not 3x as long as body or more) with 6 freely articulated segments; ocelli present; very common. Mesonotum without V-shaped suture; legs long and thin. Palps with 5 segments. Rs 4 branched. Proboscis not so long and only slightly recurved; Wing boarder rounded at apex of vein Cu2. Scutellum trilobed, with setae in 3 distinct groups; maxillary palpus shorter than proboscis. Mesopostnotum without setae; base of hind coxa distinctly ventral to base of mesomeron. Postspiracular setae absent. Prespiracular and vein Sc setae absent. Apex of abdomen tapering to a point in dorsal view, terga with basolateral patches of silvery scales. Basal pale bands on abdominal terga II-VI with 2 posterior lobes, tergum VII mostly dark scaled; lower mesepimeral setae absent. Basal pale bands of hindtarsomeres narrow, 0.2 or less than length of segment 2. Scutum with scale markings not in lyre-shape. Proboscis lacking definite pale-scaled band near middle. Hindtarsomeres pale scaled only on basal part of segment. Hindtarsomeres with pale bands. " |
